High voltage power supply is an intricate power-conversion circuit which converts a lower voltage potential to a higher one. The term “high voltage” is just a relative term and does not imply any quantity. But if voltage crosses 62 V dc, there is a possibility of bodily harm and so you should take appropriate safety measures.

High voltage power supply normally operates from AC or DC input voltages. DC input voltages are far more economical to use in the low power applications (from 1 watt to 125 watts).Typically, DC input voltages are +12Vdc and +24Vdc. AC input high voltage supply ranges from 100 Vac to 480 Vac. Whether it is a single phase or three phases, all depends on design.

A hi voltage power supply is normally seen in the following categories:

X-Ray generator

X-ray source

Rack mounts high voltage power supply

Modular one

Customized

Application-specific

It is good to consider the polarity of a DC high voltage power supply. There are units with fixed negative polarity, fixed positive polarity and reversible polarity, etc. There are some application specific power supplies that can reverse their output electronically with just a flip of switch or with a remote control signal. There are also economical units that makeuse of a permanently attached high voltage power supply circuit, while there are larger units that are used for commercial purposes. These units make use of a detachable shielded, co-axial high voltage cables.

Increasing the voltage means decreasing the flow of current, which in turn also decreases the loss of power. Hence the entire system is used in transmitting electricity at a hi-voltage. This minimizes the power loss due to the resistance in conductors. It is important to note that power gets dissipated in the form of heat. When step-down transformers are used, high voltage gets decreased for the local lines.

There are several advantages of using HVDC or High Voltage Direct Current technology. A high voltage power supply has a number of benefits when compared to the Alternating current transmission system. For instance, it enables bulk power more efficiently and quickly over long distances. But cost is an important variable in this equation. Once it is installed, this transmission system becomes an important part of the electrical power system. It improves dependability, transmission capacity and stability.

If the transmission line routes are longer than 300 miles, DC is a far better option than the AC lines because the latter has more power losses than the DC when there is power transfer in bulk.  First, the AC power has to be converted to DC to begin the process of transmission. High voltage is decreased for the local lines by making use of step down transformers. Visit www.hvmtech.com to learn much more about their amazing line of products.
